The quadratic function y=-10xsquared+160x-430 models a stores daily profit (y) for selling a t-shirt priced at x dollars. what equation do you need to solve to find the selling price or prices that would generate $50 in daily profit? what method would you use to solve the equation?

The selling price of T-shirt should be either $4 or $12.

Explanation:

The given equation is , where y is the stores daily profit and x is the price of T- shirt in dollars.

The given profit is $50.

Use factoring method to solve the equation.

Equate both factors equal to 0.

Therefore, the value of x is 4 and 12, so the selling price of T-shirt should be either $4 or $12 to earn the profit of $50.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
